Had you simply googled GBB, your questions would have been answered 100%I agree with paassatt. I am also new to the hobby and lurking around here for a while, just about the only common name I know is the GBB. Most everyone here refers to them as their scientific name.
What I did when I came across a scientific name I didn't know, I would Google it. I'm still learning, but now I find that when someone uses a common name name, I need to Google it. There is a big learning curve with all the names, but you will catch on. I have found this site (link attached) to be very helpful with the pronunciation of the names, too, should you want to learn. It can feel like learning a new language, but if you keep repeating it, you'll get it.

THISI would also suggest browsing the numerous online dealers, this will help you put names with "faces" so to speak.
Pterinochilus murinusOBT- Orange Bitey Thing (the scientific name has slipped my mind at the moment)
Or orange baboon tarantula...or Usumbarra orange...or Mombassa golden starburst...which is why P. murinus is preferred. Yeah there are a few, GBB, LP and yes, OBT that are rare exceptions to the unwritten "scientific rule" within the hobby. Because of my interest, I never had much of a problem remembering them....same for the fish I target as well, actually.Orange Bitey Thing :laugh:
